Atypical Presentation of Juvenile Hyaline Fibromatosis of Hands- A report
Juvenile hyaline fibromatosis is a rare disorder characterized by an extracellular accumulation of hyaline deposit. In the extremities, lesions may remain quiescent or gradually increase in size, eventually resulting in skin ulceration. There is no curative treatment. Surgery may allow some recovery of function, but recurrence is possible. Ruben Dukan et al report a case of juvenile hyaline fibromatosis in both hands of a 25-year-old man who required multiple surgical procedures to address problems with function, pain, and appearance.
According to history, the patient was a 25-year-old man, the first of 3 children, born of unrelated parents in France. He was right-handed and a non-smoker. There was no family history of fibrous disorders. Juvenile hyaline fibromatosis was diagnosed at age 4 years. He gradually lost the ability to walk because of bilateral knee deformity and clubfoot. At age 17 years, lower-limb corrective surgeries involving distal femoral extension osteotomy and percutaneous Achilles tenotomy were performed to improve ambulation.
The first skin lesions appeared on the face and back in childhood. Papular and nodular skin lesions, appeared progressively in the extremities, causing substantial aesthetic and functional disability. Evolution of the various skin lesion was variable, with some progressing more quickly than others. Difficulty fitting footwear and plantar pain required resection of the nodules from the feet at age 18 years. In the hands, multiple excisions were performed at ages 18, 22, and 23 years. At each procedure, careful dissection of the neurovascular structures was performed to assess their integrity and release them from compression.
Histologic examination of the excised specimen revealed JHF each time. The tumor was composed of abundant hyaline extracellular matrix embedding spindle or oval cells, which were isolated or organized in sheets. The density of the cells was heterogeneous, from scanty to moderate. No atypia, necrosis, or mitosis was observed. Successive radiographic assessment of the hands showed osteopenia and revealed both erosive and sclerotic lesions, predominantly at the distal interphalangeal joints.
At the last follow-up (2 years after the last procedure), there was no recurrence at the site of the previously resected nodules. The evolution of the other lesions and masses did not result in a loss of functional capacity, and thus did not require surgery. Despite the contractures of different hand joints related to JHF, the patient maintained functional grip and pinch capacity. He was able to continue work as a consultant. Juvenile hyaline fibromatosis had progressed in the lower extremities and the patient was confined to a wheelchair. Nevertheless, the satisfactory evolution of the hands allowed him to perform upper-limb muscular-strengthening activities, enabling him to maintain a social life and some ambulation.
